GEORGE R. LOOKVOOD, OF ST. LOUIS, MISSOURI.

COMBINED LETTER SHEET AND ENVELOPE.

SPECIFICATION forming partof Letters Patent No. 279,405, dated June 12,1883. Application med July 31,1582. (No model.)

To all whom it nfl/ay concern:

Be it known that I, GEORGE R. LOOKWOOD, of the city of St. Louis,Missouri, have made a new and useful Improvement in a Combined LetterSheet and Envelope, of which the followingis a full, clear, and exactdescription, reference being had to the annexed drawings, making part ofthis specication, in which Figure l is a view of the sheet developed,the upper right-hand corner of the sheet being turned over to show themode of applying the gum; and Fig. 2, a view of the sheet as when foldedand sealed.

The same letters denote the same parts.

In the present improvement there are ob* tained, in combination,.theseadvantages: The sheet can be readily sealed and as perfectly as in asealed envelope, and the construction is such as to offer no obstacle tothe taking of a letter-press copy.

A represents a sheet of writingpaper. It may be note or letter size, andis preferably ruled, as now indicated in the drawings. At one corner-saythe upper left-hand corner-the sheet is provided with the ilaps a an da. These aps extend from the corner at along the edges a5" a",respectively, and as far as is needed to inclose the sheet when folded,and as hereinafter explained. rlhese flaps are not gummed, nor does anyadhesive substance appear upon the face of the sheet; but upon the backof the sheet, at one of the corners, af a-saythe corner (t5-and inextent and'direction to correspond to, and, when the sheet is folded andthe flaps turned over thereupon, to come bc Vneath, the flaps, anadhesive substance, aF as,

is applied. The sheet is inclosed by folding it so as to bring that partof the back of the sheet to which the gum a7 aS is applied opposite theflaps a a-that is, the edge having the gum a? comes opposite the flap a,and the edge having the gum a8 opposite the iiap d. rlhe gunnnedportions al a8 are then moist-cned and the iiaps turned down thereuponand secured thereto, as seen in Fig. 2. rllhe lines of folding the sheetare indicated by the broken lines B C, the sheet being folded on thehorizontal line B and then on the vertical line C. In case ,the gum isapplied at the corner a", instead of at the corner a5, the sheet wouldbe folded first on the line C and then on the line B. A furthermodification is folding the sheet horizontally or vertically, or bothhorizontally and vertically, more than once. For instance, the sheet maybe folded on a horizontal line, B', and a second time on the horizontalline B2, and then, after having been folded horizontally it may befolded once or more times vertically. Vhen thus folded more than` once,either horizontally or vertically, the flaps a a are extended on theedges a a* only to opposite the lines B2 C, respectively, as indicatedby the dotted lines b2 c2, respectively.

The lines of the folds above referred to may be indicated on the'face orinner side of the sheet by ruling or dotted lines, or in any desiredway.

The sheet may be perforated at D D tofacilitate the opening` of thesheet after having been sealed.

It will be noticed that when the sheet has been folded and sealed, asdescribed, the inner side or face of the sheet is entirely inclosed, thefiaps serving to seal the only edges of the sheet which after thefolding remain Open or detached. The construction, when brought into theshape shown in Fig. 2, therefore is as effectually closed as if in anenvelope. From putting the gum upon the back a of the'sheet this benefitaccrues: The moistened sheet ofthe letter-copy book can be freelypressed against the face of the sheet A without adhering thereto, whichdifficulty is experienced when any adhesive substance is upon the faceof the sheet or its flaps.

I claim- 1. The sheet A, having flaps a. a and lines of perforation aiai, and a gummed edge, a7 as, Qn the back, substantially as described.

2. The sheet A, ruled on its face, marked at C and B, Or C Ot and B2,having flaps a af, and a gummed edge, a7 as, on its back, substantiallyas described.
